Re: [Caml-list] camlp4 char stream

[Christophe Raffalli <christophe.raffalli@univ-savoie.fr>]

OK, I found it (quote from your tutorial):

let operator_rparen =
   Grammar.Entry.of_parser gram "operator_rparen"
     (fun strm ->
        match Stream.npeek 2 strm with
	 | [("", s); ("", ")")] when is_operator s ->
	     begin
	       Stream.junk strm;
	       Stream.junk strm;
	       s
	     end
	 | _ -> raise Stream.Failure)

OK, I read your tutorial, but did not get the point ... thks

and what is the first member of the tuple ?
Why is the second member a string and not a char ?
